Abstract

To investigate the effect of the homeopathic medicine Coffea cruda on sleep pattern, it was orally administered to rats at the beginning of their waking period. EEG from the parietal region was recorded during their next sleep cycle. Applying an FFT algorithm, spectral in the band, 0.5–2.5 Hz, was chosen as a marker parameter, evaluated for control and verum groups using a double-blind protocol. Power in the verum group was statistically higher than baseline value, it was not statistically different in the control group. The results indicate that an enhancement in EEG slow delta activity is associated with Coffea cruda.
